Just out of curiousity, has anyone made a custom rear anti-sway bar. They seem pretty hard to make since they are solid profiles not hollow inside so its not even possible to bend it with a pipe bender. But anyone who has done, please leave some more details. thanks.

 

4x4max made a pretty beefy one along with custom SFCs, but IIRC it's a different design than what you're thinking about.
